[syzbot ci]

syzbot ci has tested the following series

[v1] BPF-based NUMA balancing
https://lore.kernel.org/all/20260113121238.11300-1-laoar.shao@gmail.com
* [RFC PATCH bpf-next 1/3] sched: add helpers for numa balancing
* [RFC PATCH bpf-next 2/3] mm: add support for bpf based numa balancing
* [RFC PATCH bpf-next 3/3] mm: set numa balancing hot threshold with bpf

and found the following issue:
kernel build error
